2023年8月2日 · While morphology is an important factor, do not panic if your blastocyst is not “perfect” quality! Many pregnancies do occur from AB or BB quality embryos; however, embryos with CC quality are considered non-viable and are not transferred.
Embryo Grading & Success Rates: The Sensible Guide
Knowing the components of a blastocyst is key to understanding its grade and likelihood of a successful pregnancy. A blastocyst is distinguished by its two clearly defined cell components and a fluid cavity. The quality of the blastocyst describes how clearly formed are these structures.
Blastocyst quality and reproductive and perinatal outcomes: a ...
Blastocysts were graded individually based on assessment of the morphology and development of the inner cell mass (ICM) and trophectoderm (TE), and were grouped into three quality categories: good- (AB, AB, or BA), moderate- (BB), and low-grade (grade C for ICM or TE) blastocysts.
